Case Report
Orbital metastases are very rare, particularly as an initial presentation feature of occult breast cancer. This is a case of orbital metastasis from an occult lobular breast carcinoma in a woman in her mid-70s, who presented with symptoms of gradual visual deterioration. Prompt and extensive investigations led to the diagnosis of metastatic orbital lobular carcinoma in the absence of clinically or radiologically evident primary breast cancer. This occurred independent of a previously treated ductal breast carcinoma history.
